branch: master
commit 04ad96f55463451babdaf7f7a9e29972eeedbcca
Author: Patrice Dumas <pertusus@free.fr>
AuthorDate: Sat Nov 16 23:25:22 2024 +0100

    * nstall-info/install-info.c (split_entry): cast argument of isspace
    to unsigned char.  This is recommended as this function expects
    unsigned argument, and it avoids warnings with -Wchar-subscripts when
    the function is implemented with an array.
